"American 100-meter record holder Tyson Gay has tested positive for a banned substance and says he will pull out of the world championships next month in Moscow.

Gay isn't revealing the substance, but he says he was notified by the U.S. Anti-Doping Agency on Friday that a sample came back positive from an out-of-competition test May 16. He says he will have his "B'' sample tested soon.

The 30-year-old Gay fought back sobs in a phone conversation Sunday from Amsterdam, saying: "I don't have a sabotage story. ... I basically put my trust in someone and was let down."

Gay was healthy again this season after being constantly plagued by hamstring and groin ailments, along with a surgically repaired hip. He won the 100 and 200 at nationals last month."

widely? I recall it being a matter of hours, NOT days. besides that, even if it was a day and a half, it's NOT going to be 108 in the car while the guy is driving it, even euro cars have AC, then its also not going to be 100+ at night, so that leave a matter of hours for it to be "warm". i, and many other still feel that lagat got supremely lucky on that one. notice he's never run close to those times since then~

I think it's widely accepted that Lagat's sample was fd.It was kept in a car for days in high temperatures. Test a sample under those conditions scientically and you see what happens.

EPO was used three days per week during the "corrective phase", which is the first two weeks of a cycle. This substance provides a big advantage to sprinters because it enables them to do more track repetitions and obtain a much deeper training load during the off season.

It is most likely Gay is telling the truth and therefore innocent. Athletes put so much trust in agents, coaches and other assisting staff but often these are the very people who would let us down just like any family. And when you fail a drug test, you are left to shoulder the shame on your own, with each one of these people pointing fingers at you. It is very sad for those genuinely innocent especially when you consider the amount of work they put in day-in day-out. Agents and these other "assistants" have a motive here-to make as much money as they can while you are still healthy and productive. Iaaf should hear the athletes' side of the story and if someone really "spiked them up", they should be given a lenient punishment.
